Foamed polystyrene waste can also be used to do other products

With the rapid development of petrochemical and plastic industry, plastic products have been widely used in industrial and agricultural and daily life. As the polystyrene (PS) after the foam has a low density (25 kg / m3), low water absorption, acid and alkali, good sound insulation, and shock, can be decorated, easy to shape, etc., so in building materials, household appliances aspects of a wide range of applications, but also caused a more serious white pollution, the recycling rate of less than 20%. Abandoned foam PS if buried, because it is not easy to aging and difficult to degrade, will pollute the underground water, destruction of soil structure, so that grain and other crops cut; such as simple incineration, it will seriously pollute the air and atmospheric environment.

In view of the above problems, people have to explore and practice the use of foamed polystyrene waste for chemical building materials industry, and achieved satisfactory results, creating a considerable economic benefits. And Styrofoam recycling is a good choice.

Application of Foamed Polystyrene Waste

1. Light roof insulation material

Crushed waste foam PS, adding expanded perlite and cement, mortar, and then  mixed after the roof placed on the maintenance of 3 days, naturally dry, and then with the cement mortar smooth into a lightweight concrete insulation layer. The method used to produce the material production cost is low, and has a good insulation.

2. Waterproof membrane

The waste foam PS wash, dry, with cheap benzene or chlorine hydrocarbon residue dissolved, adding toughening agent and film-forming anti-wear agent to reconcile into a viscose-like, blown or coated on the glass cloth surface, dry After the waterproof membrane, can be used for roof or pipe waterproof. The solvent can be recycled after cooling.

3. Fiber reinforced insulation board

The waste foam PS crushed into 0.1 ~ 0.5 cm particles, adding cement and fiber reinforced mixture, and fully mix, and conservation, can be made of excellent mechanical properties of lightweight sheet, it also can be pre-made into a composite wall, indoor insulation noise board, block, can also be used for on-site pouring.
